Abstract
The utility model relates to a cloud platform mechanism for camera and video camera, which is the cloud platform locking mechanism designed to solve the problem of poor stability in prior cloud platform locking structure. The ball body of the mechanism is arranged in a cloud platform ball sleeve, the ball body bottom is in contacting connection with a press block. The technical proposal is that a fixed block in the cloud platform is fixed in the ball sleeve, and the fixed block is provided with a fixed block inclined plane and a fixed block sliding plane; symmetrical press block inclined planes are arranged at the press block lower part, one press block inclined plane is in contacting connection with the fixed block inclined plane, and the other press block inclined plane is in contacting connection with a pushing block inclined plane, and the pushing block is connected with the fixed block sliding plane; a screw rod is connected with a locking handwheel, the screw rod is inserted in the ball sleeve, and the screw is connected with the pushing block. With the additional contacting plane between the locking mechanism and the ball body, the friction and the locking force in the utility model can be strengthened when locking. The mechanism has the advantages that the structure is simple, the design is reasonable, and the locking is firm; thus being applied to the inner ball body angle regulation and locking in camera or video camera.
Description
Technical field
The utility model relates to the mechanism of camera, projection camera The Cloud Terrace, is a kind of The Cloud Terrace locking mechanism.
Background technique
At present, the camera of selling on the market, projection camera, great majority are to regulate angle of shooting by the universal spheroid in the The Cloud Terrace, and the locking mechanism of universal spheroid bottom is locked universal spheroid, thus the establishing shot angle.The locking mode of its locking mechanism is a lot, as the patent No. ZL200620067557.8 that discloses in the Chinese patent literature, November 21 2007 notice of authorization day, model utility title " a kind of photography The Cloud Terrace ", connect eccentric shaft in the rotatable handle, touch face and spheroid bottom on the loose collar and touch the face contact and is connected, the semi major axis by eccentric shaft contacts with the following face that touches of loose collar, locks spheroid.The spheroid bottom surface of contact of its spheroid and loose collar is less, and frictional force is less, the locking mechanism less stable, heavier as camera, projection camera, angle of shooting is in horizontal plane, centre-of gravity shift during shooting, the stressed excessive displacement that is easy to generate of univesal sphere, and angle of shooting changes.
Summary of the invention
The utility model is the deficiency that overcomes above-mentioned existence, and purpose is the The Cloud Terrace locking mechanism a kind of reasonable in design that provides to related domain, makes it can solve the technical problem of existing The Cloud Terrace locking mechanism less stable.The purpose of this utility model realizes by the following technical solutions.
A kind of The Cloud Terrace locking mechanism, the spheroid of this mechanism place in the ball cover of The Cloud Terrace, and contact is connected with briquetting in the spheroid bottom, and its main points are that the fixed block in the The Cloud Terrace is fixed in the ball cover, and fixed block is provided with fixed block inclined-plane, fixed block sliding surface; The briquetting bottom is provided with the briquetting inclined-plane of symmetry, on one side briquetting inclined-plane contact be connected and fixed the piece inclined-plane, the briquetting inclined-plane contact of another side connects the pushing block inclined-plane, pushing block is connected with the fixed block sliding surface; Screw rod is connected with the locking handwheel, and screw rod inserts ball cover, and screw rod is connected with pushing block.Tighten the locking handwheel, screw rod promotes pushing block and inwardly slides, pushing block lifting extruding briquetting, locking spheroid; The accent tight handwheel that uncages, screw rod outwards withdraws from, and spheroid is subjected to gravity, spheroid extruding briquetting, briquetting drives pushing block and outwards slides, and spheroid unclamps.Because it is bigger that the inclined-plane connects the surface of contact of relative horizontal plane connection, locking back frictional force is big, and locking effect is good.
Described ball cover is provided with snap ring, and snap ring is connected with fixed block, and fixed block is fixed in the ball cover, prevents that fixed block from relatively moving.
Described briquetting top is provided with the arc disc, and the arc disc is provided with packing ring.Spheroid places briquetting arc disc, has increased rubbing surface; The packing ring of arc disc increases the frictional force between spheroid and briquetting.
The utility model has increased the surface of contact of locking mechanism and spheroid, the frictional force when strengthening spheroid locking, tightly locks power, has simple in structurely, reasonable in design, simple to operate, tightens firm characteristics, is applicable to the angle adjustment and the locking of camera, projection camera interior spheroid.

Embodiment
Mode of execution is an example with practical operation of the present utility model.Spheroid 1 places in the ball cover 2 of The Cloud Terrace, and snap ring 8 is fixed in the ball cover, is connected and fixed piece 7.Screw rod 5 and locking handwheel 6 fixedly are connected as a single entity, and screw rod inserts ball cover by screw thread rotation.Pushing block 4 slides on fixed block sliding surface 72, and the briquetting inclined-plane 31 of briquetting 3 bottom symmetries is connected with pushing block inclined-plane 41,71 contacts of fixed block inclined-plane respectively.Regulate pushing block by the rotational lock handwheel, its working principle is as follows:
The locking handwheel that turns clockwise, the locking handwheel drives screw rod and rotates, and screw rod promotes pushing block and inwardly clamps briquetting.At this moment, pushing block inclined-plane and the acting in conjunction of fixed block inclined-plane promote the briquetting lifting, and spheroid is locked in extruding, has promptly finished the locking action of The Cloud Terrace.Be rotated counterclockwise the locking handwheel, screw rod outwards moves, the generation gap between screw rod and the pushing block.Because gravity, spheroid pushes briquetting downwards, and briquetting pushes the pushing block inclined-plane downwards by the briquetting inclined-plane, and pushing block outwards moves, and can finish the action of unclamping of The Cloud Terrace.
The utility model is simple in structure, and coupling mechanism force is big, and The Cloud Terrace can bear heavier camera or projection camera and loosening.According to above-mentioned embodiment as can be known, the utility model is to promote pushing block by screw rod, and pushing block inclined-plane and fixed block inclined-plane clamp the lifting briquetting, and locking firmly places the spheroid on the briquetting.The technician of relevant industries does conspicuous technological improvement according to general knowledge, all belongs to design category of the present utility model.
